Speciiiia'ii Ioriningpart of Letters Patent-Nof'll, dated January 5, 1864.

" the saine is fully described and representrd in the following specification and accompany.-

Aing drawings, letters, figures, and references thereof.

Figure 1 represents a longitudinal and vcrtical section of my refrigerator.

The great difficulty with all ventilaed refrigerators has been lthe rapid decay of ice, caused' by4 the leading of' too much warm air onto the ice, or onto a surface cooled by the` ice. When warm,- air is brou"li't inimmdiate" cintact'with ice, it will me t it with great rapidity, and if a solid surface is placed between the ice and the air, and if the air is made as cold as when brought in immediate contact with the ice, it is evident it requires preciselyv as much ice to accomplish it.

In Letters Patent granted to me January 1, 1861, for an improved refrigerator, I use the ice-meltings to cool the air down to a lower temperature before the air passes over the ice, thus reducing the rapid decay of the ice, and in which refrigerator it will be perceived I allow the air to pass over the ice and to come in immediate contact with it after being partially cooled by coming in contact with a surface submergedin the ice-ineltings. It is therefore evident that in my refrigeratorof 1861, and in all ventilated refrigerators, the icc has been employed to doall the work of ventilation, refrigeration, and desiccation, be` cause the moving atmosphere has been led through the icechamber and into immediate contact with the icc before it passed into the preserving-chamber.

The great object of my improvementherein described is to ventlate a. refrigerator without either passing air over the ice, or a solidsurface cooled by ice, or even to lead either the internal or external air into the ice cham` ber, thus necessarily economizinggreatly in the use of ice, and at the same time preserving all of the cooling and drying qualities.

in order that my improvement-'may be bet-l ter understood, and that others may-be enabled to construct it, I refer to the annexed drawings and letters and figures of referenceA marked thereon.

A is the ice chamber. B is the horizontal plate or receptaclefor the meltings C is the preserving-chamber. d is the extended arm or end of the horizontal plate or receptacle B, reaching nearly to the top of the preserving chamber. e is the opening between the top of the arm d and the top of the preservingchamber. j" is an opening in the front of the pneserving-chamber for the exit of air when desired. g is an opening for the admission of external air into'the receptacle when desired, made at a point higher than the exit-opening f. l li :isthe opening to allowthe cold air to fall from theplate or receptacle B into thepreserving-chamber C. k k is thedrainpipe 'toiear'ry off th'm'eltings, which, when the meltings are to be collected, is made to reach a certain distance above the door, so as to compel acertain depth of meltingsl to be'collected before they are 'allowed to flow off. m m represent. the accumulated ice-meltings.

y y When ice placed in the ice-chamber A, the openation of my refrigerator is as follows, viz The ice will naturally melt, and the meltingswill drop through and fall on the plate or receptacle B, and be collected to a certain depth before they are allowed to flow out through the drain-pipe k 7c. The air in the preserving chamber U is warmer at the extreme top, near opening e, than at an y other point. This being v the case, it will flow through opening cinto receptacle B, lbecause the meltings and the air Ain the receptacle are colder than the in tiowing air. This iniiowing air will become colder than" before by passing over and coming in im mediate contact with the cold drippings of the ice and the ice-meltings after they are col-V lected, and mingling with the stationary cold air in receptacle B, and, of course, as its specific gravity is increased it will fall through opening h into preserving-chamber C, and as this air passes over warm meats, 85o., it will take up the heat in its passage and rise to the opening e and pass again into receptacle B, and 'so rotate and, circulate from chamber C to receptacle B, and from receptacle B to 'chamber C; but when I desire to ventilato' by using the outside air, I open the double register covering openings g and f,'and the loutside 'L1-ir will flow into receptacle B through l nrrangedtliat the air for ventilation will enopening g and becon'ie Acold py owing over i ter it at a point above where it Hows out into the ice-melt-ings land mingling with the lripthe preserving-chamber.

pings as they fall from the ice, and, mixing 1 2. The combination ofthe open-bottom ieelwith the cold air in the yreceptacle,'will 4then fall, and, passing; over warm' meats, 86o., will g chmnber A, the receptacle or plate B, with its arm d, and l'ie provlsion-clmmber '(J, all so rise and flow out of openingf, thus producing arranged that' the interxml air will be mzu'ie to a current of :tir continually through lthe preserving-chamber, and all air that does not escape atjin its passage will rise to e, and, passing into receptacle 13,' will continue its rota.-

Vtion and circula-tion,-

What I claim as my invention, and desire'to secure by 'Letters Paten t, is- 1. The'peeuliar construction of the plate or receptaele'B,l1aving anextended arm, d, so 1 l rotate 'and circulate, and' the external air willpass in vcurrents throughthe provisionchamber, the vWhole arranged and operating sul)- set forth.
